Patent GB-1075300-A (GB)
Title: N-substituted-5-sulfamoyl-4-trifluoromethylanthranilic acids
IPC: C07D333/20
Filed: 1966-05-24
Abstract: The invention comprises compounds having the formula <FORM:1075300/C2/1> wherein R1 is a hydrogen atom or a C1- 6 alkyl group, R2 is furylmethylamino, thenylamino, benzylamino or dibenzylamino and carboxylic acid salts thereof.  The novel compounds may be made by nitrating a 2-halo-4-trifluoromethylbenzoic acid to give a 2-halo-5-nitro-4-trifluoromethylbenzoic acid, reducing this to a 5-amino-2 - halo - 4 - trifluoromethylbenzoic acid, treating this product with conc. HCl and sodium nitrite followed by SO2 in acetic acid containing cuprous chloride, treating the resulting 4-chlorosulphonyl compound with ammonium hydroxide or an alkylamine to give a 2-halo-5 - sulphamoyl - 4 - trifluoromethyl benzoic acid and reacting this with R2H to give the desired product. Alternatively, a 2-bromo-5-trifluoromethylanilin is converted to 4-trifluoromethylanthranilonitrile. This benzonitrile may be reacted with chlorosulphonic acid and ammonium hydroxide or alkylamine to give 5 - sulphamoyl - 4 - trifluoromethylanthranilonitrile which is hydrolysed to the corresponding anthranilic acid.  Alternatively, the benzonitrile may be hydrolysed first and then sulphamoylated.  The 5-sulphamoyl-4-trifluoromethylanthranilic acid is reacted with RCHO in which R is phenyl, furyl or thienyl and the resulting Schiff base is reduced to give the desired N - substituted - 5 - sulphamoyl -4 -trifluoromethylanthranilic acid.ALSO:Pharmaceutical compositions having diuretic activity comprise a pharmaceutical carrier in association with an N-substituted-5-sulphamoyl - 4 - trifluoromethylanthranilic acid of the formula: <FORM:1075300/A5-A6/1> where R1 is hydrogen or alkyl having 1 to 6 carbon atoms and R2 is furylmethylamino thenylamino, benzylamino or dibenzlamino, or a carboxylic acid salt thereof, with or without a 2,4,7-triamino-6-phenyl pteridine of the formula: <FORM:1075300/A5-A6/2> where R3 is hydrogen or alkyl having 1 to 3 carbon atoms and R4 is hydrogen, alkyl having 1 to 3 carbon atoms, trifluoromethyl, halo or alkoxy having 1 to 3 carbon atoms.  With a solid carrier, the composition may be in the form of tablets, hard gelatin capsules, troches or lozenges.  With a liquid carrier, the composition may be in the form of a soft gelatin capule or a liquid suspension.  The compositions may be administered orally or parentally

Title: Improvements in panoramic cameras
IPC: G03B37/02
Filed: 1920-08-07
Abstract: 174,105. Stromberg, J. E. Aug. 7, 1920. Panoramic cameras.-In a camera of the kind in which the camera is rotated bodily round a vertical axis by a spring motor, an adjustment is provided for moving the camera backwards and forwards relatively to its fixed support. The camera is carried by a tripoc, on the head of which is a fixed circular rack 5 engaged by a pinion 6 driven from the spring 18 through bevel gearing 17, 16, 10, 9. Beneath the camera body are runners 1<b>, Fig. 9, engaging guide members 34a on a plate 34<b> mounted on an axle 1<a> freely rotatable in a bearing in the tripod head. By means of the rack-and-pinion gear 34 the body 1 is moved relatively to the plate 34<b> to disengage the pinion 6 from the rack 5, thus allowing the use of various sizes of pinions to compensate for different extensions of the lens. The film is wound from the spool 19 on to the spring-driven spool 20 and passes over guide-rollers 28, 29 and through an exposure slit in front of a focussing- screen 25. The edges of the film are perforated and it is driven from the shaft 17<a> by pinions 17<c> which engage idle rollers 17<d> for holding the film in the exposure plane. The upper of the two pinions 17<c> and the upper portions of the spoolholders are adjustable vertically so that different widths of film can be accommodated. The speed of rotation of the camera is controlled by an adjustable governor 14 driven from the pinion 12,. which is slidably mounted on the shaft 10<a> so that'the governor can be disengaged when desired.. For stopping the rotation of the camera a brake drum 11 is provided on the shaft 10<a>, and the braking-member acting in conjunction therewith is applied by the spring 30<b> and withdrawn by operation of the arm 31. During the rotation of the camera the brake is held in the " off " position by a lever 7<a> and a spring catch 7, which is tripped at the end of the exposure by an arm 5<a> on the tripon head. The catch 7 is provided with a pivoted extension to engage the arm 5<a>, and this can be set so that the catch is tripped only at the second engagement with the arm. Simultaneously with the application of the brake a door 25<a> in front of the exposure slit is closed by the links 25<a>, 25<b>, 25<c>, 25<d>. Focusing on the screen 25 is effected through a slot in the film, and additional side screens 25f are provided so that the image can be focused irrespective of the position of this slot. The camera is also adapted for use with plates in the ordinary manner. The plate-holders are inserted through a door in the top or side and are held against a fixed frame 37<1> by spring bars 37<k>. The frame 37 holds a focusing-screen, portions of which are pivoted so that they can be swung aside to allow access of light to the film and the focusing screens 25f. The image on the focusing-screen for plates is viewed by mirrors 35, 36, the latter of which can be moved vertically by cords passing over pulleys.

Title: An improved method for remote control
IPC: H02J13/00
Filed: 1951-10-08
Abstract: 732,351. Electric selective signalling. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Oct. 8, 1951 [Oct. 9, 1950], No. 23398/51. Class 40 (1). In remote control systems wherein control operations are selected by the time interval between a " starting " and a " performance " audio frequency impulse superposed on the normal electric supply network, incorrect operation of a receiver by two " performance " impulses P initiated for example, in different control systems, is prevented by arranging the time interval t1, t2, t3 ... between a starting impulse B and any associated performance impulse P1, P2, P3 ... to be an uneven multiple for example, 3t, 5t, 7t ... of an elementary time interval t, whereas the interval between performance impulses is an even multiple, for example 2t, of the elementary interval. Each receiver is constructed as in Specification 687,333, so that, having responded to a first impulse, be it a starting or a performance impulse, it is locked against operation by a second pulse occurring thereafter at any even multiple of the elementary time interval t, as shown at H. The receiver can therefore respond completely only to two impulses displaced by an uneven multiple of t. Specification 728,729 also is referred to.
